ANSWER KEY AND JUSTIFICATIONS
- B – 3 + 2 = 5. Counting apples involves addition, which is fundamental to early math.
- A – After 7 is 8. This question checks understanding of cardinal numbers sequentially.
- A – Counting by 2 from 0: 0, 2, 4, 6, 8, 10, 12. This tests skip counting proficiency.
- B – 1st is an ordinal number indicating position. This question aims to differentiate between types of numbers.
- A – 6 – 2 = 4. Basic subtraction is employed here to foster simple calculation skills.
- D – 9 is both odd and a prime number. Understanding properties of numbers is crucial in early mathematics.
- A – Counting by 5: 0, 5, 10, 15, 20, 25. Before reaching 25, 20 is counted. This emphasizes skip counting comprehension.
- B – The 1st car is red; the color is predetermined. This ensures understanding of ordinal positioning.
- B – Mike is in last (3rd place). Recognizing ordinal numbers helps understand competition results.
- A – 7 + 3 = 10. Simple addition is key in foundational math skills.
Remember, practicing these questions will help you understand how to use numbers better!
